Title: EPA’s Energy Performance Rating System
1EPAs Energy Performance Rating System
May 13, 2008
2Be a Leader Change Our Environment for the
Better
- U.S. EPAs ENERGY STAR
- The U.S. Environmental Protection Agency (EPA)
can help you with buildings and plants to - Reduce energy waste
- Reduce GHG emissions
- Protect the environment
3Need for a Rating System for Buildings
Is 80 kBtu/SF/YR high or low for a building?
Statement of Energy Performance EPA Rating
Fuel Efficiency MPG
Is 60 MPG high or low for an automobile?
4Benchmarking The First Step to Energy Savings
in Buildings
- Benchmarking through ENERGY STAR allows you to
- Compare one building against a national sample of
similar buildings - Compare all of your buildings of a similar type
to each other - Set priorities for use of limited staff time
and/or investment capital
5Portfolio Manager Helping You Track Your
Performance
- Free online tool where you can
- Benchmark the energy use of all of your buildings
all will receive an energy use intensity (EUI)
and some will receive ratings on a 1-100 scale - Track changes in energy use over time in single
buildings, groups of buildings, or entire
portfolios - Track cost savings and CO2 emissions
- Apply for ENERGY STAR recognition
- Track water usage

- Establish portfolio baseline, set goals, measure
and track performance over time - Verify gains from upgrade efforts
- Require specific rating gains from service
providers in select building types such as office
or warehouse
14Rating Interpretation
Once you have established an energy performance
baseline rating, you are ready to set improvement
goals and create an action plan. The guide below
can help you interpret the ratings and determine
appropriate next steps.
15Portfolio Manager Features
- Master account feature
- View (and Reporting) Options
- Statement of Energy Performance
- Percent energy reduction
- Water tracking
- Automated benchmarking
- Multi-Facility Meter Update
16Tracking Campaigns Master Accounts
- Objective Allows colleges and universities to
track progress of campaigns, for example - University systems can track individual campuses
- Energy saving competitions among residence halls
or other buildings - Process
- Institution creates a Master Account
- Master Account appears in a public registry
- Individual users can share facilities with Master
Account - Master Account holder can view progress for all
facilities that have been shared
17View (and Reporting) Options
- The My Portfolio page uses views to display
summarized data - A view is a set of columns that display various
data in a table - Portfolio Manager provides the ability for a user
to create their own view by selecting the columns
(up to seven at a time) to display on the My
Portfolio page - It also enables the user to select the number of
facilities that can display on the My Portfolio
page (e.g., 25, 50). There are over 30 different
data columns that can be selected - Any view can be set as the default view and these
views can be downloaded into a Microsoft Excel
spreadsheet for further analysis
18Statement of Energy Performance
- Objective The SEP can be generated for purposes
other than applying for the ENERGY STAR Label - LEED-EB certification process
- Real estate transactions
- Maintaining a Facility Summary Report
- Process
- User selects time period of performance
- Tool generates 1 page summary with energy use,
cost, and emissions figures - Summary also included as second page when full
SEP is generated to apply for the ENERGY STAR
19Percent Energy Reduction
- Objective Provide a metric to show a percent
change in energy use over time - Creates tracking capability for all space types
- Process
- For non-ratable spaces the tool compares weather
normalized source energy use between two periods
and adjusts for any changes in square footage - For ENERGY STAR ratable space types, the tool
compares energy use between two periods adjusting
for changes in weather and business activity
20Water Tracking
- Objective Allow users to track water use in
Portfolio Manager - Continued emphasis on tracking all utilities
- Lay groundwork for understanding the
relationships between water and energy use - Process
- User can select Add Water Meter for any
facility - User can identify water meters as indoor,
outdoor, or wastewater - Tool displays water use totals for any 12 month
period - User can compare two different periods and track
over time - Upcoming Enhancement percent change between two
time periods will be displayed
21Multi-Facility Meter Update
- Objective Provide the ability to easily update
meter data for a large number of facilities,
greatly increasing the efficiency for meter
updates - Process
- Users select the facilities in their portfolio
(maximum of 250 per download). A Microsoft Excel
spreadsheet lists each facility and the specified
number of meter data entries (billing cycles) - Once meter data is entered and saved, the
spreadsheet is uploaded. Users can review and
edit the data before uploading it to Portfolio
Manager - This feature is used to update meter data it
will not overwrite or replace meter data that
already exists in Portfolio Manager
22Automated Benchmarking
- Allows utilities and energy info service
providers to - Securely exchange building and utility data with
the EPA ENERGY STAR program - Leverage the ENERGY STAR rating within their own
systems - Reduce the burden on energy end users of
benchmarking their energy performance
23Recognition Opportunities for Eligible Spaces
